I've done a little turkey hunting through the years, mostly with my dad, who is really into it. But, I'm planning to do more, and my dad surprised me with a new Mossberg 835 a few months ago. So, with turkey season coming up, I decided it was time to get it out and shoot some patterns.
So, I got to the range yesterday (which was PACKED with people) and started out at 25 yards with some 2 3/4" game loads just to see if the sights were close. They weren't. I shot twice, and both shots were probably 10" high. The crowd was so bad at this point, I decided to just go home. When I got home, I started looking at the sights, and I don't have any adjustment left to lower the rear sight. I did a little internet searching, and I see that this is apparently a common problem with the 835.
The front sight needs to be taller, or the rear needs to adjust lower.
So, a couple of questions:
1. Is there any DIY fix without buying new sights? I'm in a hurry.
2. How do the factory sights come off? They don't seem to have screws. Are they just crimped onto the rib?
Many shotguns shoot high. It is common because wing shooters like to be able to keep the bead below a bird in order to not cover it up with the barrel. However I also agree that Mossberg is not putting much into these sights they are using. I really think you would be happier once you replace them with aftermarket sights such as Tru Glo Magnum Gobble Dot Pro Series or the new Tru Point Extreme or Williams fire sight or an optic.
The current sights are indeed just clamped onto the rib. I was able to use a soft wood popsicle stick clipped off straight to push up along the clamp and work it off.

Great, thanks! I looked at them last night, but I was a little hesitant to start prying on them this close to the season with me not knowing if that's how they came off.

Yeah, I didn't like the looks of the flimsy rear sight from the beginning. I think I will end up replacing them, but I don't know if I'll be able to do it before my first hunt.
Thanks again!
I'm just throwing this out there. But did the gun come with different size stock shims? And would adding these help with it shooting high at all?
When I first got mine I inquired about the high POI. It was explained to me that the sights were like that on purpose so that out to 50 yards with a turkey load you could hold on the base of the neck and kill your bird. This was so your target was always in sight and not overed up by the front sight. I went out and drew a to scale turkey head and neck. With the lower neck hold it was perfect. Even close shots were right where they were supposed to be. It impacts much higher with the lighter loads which I think you have already learned. reflexl

Really? I'm certainly no shotgun ballistics expert, but this seems very unlikely to me. Different loads are going to impact differently, but surely not to this extreme? And, I just can't see a "game load" shooting 10" high at 25 yards and that being by design. I was always taught to hold a couple of inches below the head, because that's where you want the center of your pattern to be.
Also, I did discover last night that the rear sight wasn't seated all the way down on one side. I don't think that will fix the entire problem, but maybe it will help.
When it was new my 835 shot high. The sights are clamp fit on the rib. I took off the front sight and cut a piece of thin flexible refrigerator magnet to fit between the sight and rib which raised up the front sight and lowered the P.O.I.. Now my sights are dead on. Ive hunted with this gun now for several years and the sight has never came off.

Funny, I was trying to think of a material to use for that same thing yesterday. Flexible magnet is a good idea. How thin is "thin"? I don't know how high I'll need to raise the front sight to drop the poi as much as I need. But, if the shim is too thick, it will have to be held down with screws because the front sight won't be able to clamp it to the rib.

No stock shims came with the gun. I think that only works with a bead and wing shooting anyway though. With rifle sights, lined up is lined up, as far as I know.

Really, really. My $1500 SBE II shot almost a foot high at 30 yards! Emailed Benelli and their response was just that. 60/40 pattern and that they only guaranteed poi to poa within +/- 6" elevation and +/- 4" for windage. That's with a gun costing almost FOUR TIMES what I paid for any one of my 7 835s. A shim change, and yes, you can buy them for the 835, was all it took to bring poi back down and though I run it with a red dot sight for turkey, its dead nuts with just the rid for everything else. I would recommend either pickng up a set of better, adjustable sights or mount a sight of some kind d as the 835 is already drilled n tapped...

I'm not trying to be argumentative, but just because it's all they'll guarantee doesn't mean it's what a shotgun is supposed to do. Why would it ever be desirable for a turkey gun to shoot a foot high?

How do shims in the stock change the poi when using rifle sights? I'm open to explanations, but I just don't see how the laws of physics allow it.

I'm definitely going to put some better sights on it sooner or later. Even if I get the ones on it adjusted to shoot right, I don't like them. The rear sight looks like it's one snagged branch away from being bent at a 90 degree angle.
If you are in a rush and have to shoot with the sights you have you need to go back to range with a life sized turkey target, hand drawn will work, and shoot the loads you will be hunting with at a normal hunting range for you and determine your point of aim on the actual turkey. I have one turkey gun of several that I own (Mossberg 20 ga bantam turkey) that shoots high. We did this , determined the hold was about 8" low , so we aim a little below the waddles with this gun. Only one grandson shoots it and he remembers this. Ideally we would replace the sights but he's outgrown it and it will probably go away. You can do this until you get the sights changed.

Never said it was. That's for wingsooting and for those that don't bother to use or like to use a sighting system of one sort or another.
Again. for use with the vent rib and bead(s) this WILL lower your poi. The non-adjustable "sights" you have on the gun now are about useless if it's shooting that high and you have no way to adjust wouldn't you say?
A $30.00 set of replacement sights that CLAMP, not glue or stick on the vent rib is what you'll want to look for. I have purchased many a shotgun with those lousy stick on "sights" on them and they are the very FIRST thing I replace before I even bother to fire a single shot. They are pure garbage and imo, only put on as an after thought by the company.
Good luck getting that gun shooting! :icon_thumright:
Yep really. Original sights still in place. And also yes light loads have always shot much higher in the gun. reflexl

I think the magnet was .075 thick. Didnt effect the clamp of the front sight and its held in place for several years. My gun is a 835 Grand Slam.
Truglo magnum gobble dot pro series fixed mine. The front sight sits higher, plus the rear sight is fully adjustable for elevation. I've got an 835 that shot high, but now shoots dead on. I never want a gun that I have to consciously adjust my aim so it will shoot where I need it to, because in the heat of the moment it's easy to forget. I need a gun to shoot exactly where I'm aiming so it takes all the guesswork out. Also, I found a fiber optic rear ghost ring that I paired with the front sight from a Truglo Magnum Gobble Dot Pro Series set. Put them on my 935 and I absolutely love it.
Thanks for the all the replies, guys. I made a shim and put it under the front sight. I managed to get back out to the range and shoot yesterday. It's a fix that works for now. It looks like I'm not going to hunt the first weekend, so I may have time to get some better sights on it before I take it to the woods.
And, on a related note, I tried 4 different loads, and all of them will kill a turkey dead at 50 yards. So, we're good there, at least.
I have fixed at least half a doz new Mossberg 835s with the same problem. You HAVE to loosen the rear sight and slide it back down the rail. As the rail gets closer to the stock, it drops. This puts the rear sight lower causing you to move the front of the bbl down and drop the shot. Seriously have done this and helped the last 4-5 people that bought the same gun. The shimon the front sight is basically doing the same, but eliminating a fail factor such as a shim, and keeping the sight bolted directly to the rib, WILL fix the problem. Slide it back an inch or so till it slides down and lock it in...
His sights are the stick on type, non-adjustable version.

I wondered if that would make any difference. There's some room to move the rear sight back, but I didn't really think that would lower it any. Apparently I should have tried it.

The rear sight has an adjustment screw, but it was as low as it would go already.
Had the exact same problem with my 835. POI was 12" high @ 40 yards. Fixed it with a dnz mount and a Simmons Prodiamond 4x scope.
I went ahead and ordered a Williams Fire Sight. It should be here monday. I'm not going to be able to hunt this weekend anyway, so no big deal.
Just be glad that it shoots high, and not low, or off to one side. If it shoots less than a foot high, just aim at the waddles.

^^^^X2^^^^ Aim for the waddles 20 yds and in, Aim for the base of the neck 25 - 40. IMO 60%-70% of your pattern needs to be above your line of sight so you can see what you are shooting at. That is my preference anyways.
